Water
The water used to homebrew can lead to different tasting results. Historically, beers have been made using different ratios and amounts of minerals within the water based on where the beer is made and where the water is sourced from. For advanced homebrewers, this hardness, as well as the pH level of the water, can be manually created. Using reverse osmosis water as a base, due to its minimal mineral content, a homebrewer can add in the desired amount of different minerals to achieve a water hardness that enhances the taste of the beer.
